Description

Technical Field

[0001] This utility model relates to the field of wind turbine generators, and in particular to a positioning device for processing wind turbine blades. Background Technology

[0002] A wind turbine is an electrical device that converts wind energy into mechanical work, which drives a rotor to rotate and ultimately outputs alternating current. A wind turbine typically consists of components such as a rotor, generator, deflector, tower, speed limiting safety mechanism, and energy storage device. During the manufacturing process of wind turbine blades, positioning devices are required to ensure stability during processing.

[0003] A search revealed the Chinese patent "Wind Power Blade Curved Surface Positioning Fixture" (CN222537465U). This utility model relates to the field of wind power blade processing technology, specifically a wind power blade curved surface positioning fixture. It includes a base, a carrier block fixed at the top center of the base, and an adjusting plate fixed to one side of the top of the carrier block. Frames are connected to the upper and lower inner walls of the adjusting plate, with the lower frame fixed to the top of the carrier block. The two frames are symmetrically arranged. A limit plate is fixed to the inner wall of each frame. Multiple evenly distributed lifting columns are movably inserted through the surface of the limit plate. One end of each lifting column is connected to a rod, and a clamping block is fixed to the outer end of the rod. This utility model achieves initial blade positioning by closing the two frames. Then, multiple servo motors drive screws to rotate, thereby driving the lifting columns to rise and fall, which in turn causes the clamping blocks to adhere and press against the outer wall of the blade. Multiple clamping blocks adhere to different positions to ensure a good fit for blade positioning, thus ensuring stable positioning and guaranteeing the accuracy of blade processing.

[0004] Although the aforementioned wind turbine blade positioning device can clamp and position the blade on a curved surface by using multiple lifting columns and their end abutment blocks to move perpendicularly to each other, the abutment blocks are semi-circular in design while the surface of the blade is basically flat, resulting in a small contact point. In addition, if the blade is fixed in a part with a small curvature, the vertical lifting columns and abutment blocks on the side may not be able to fully contact the surface of the blade, resulting in missing connection points and affecting the stability of the blade during processing.

[0005] Therefore, a positioning device for wind turbine blade processing is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a positioning device for processing wind turbine blades in order to solve the above-mentioned problems, thereby improving the problem that the positioning device for processing blades cannot be applied to parts of the blade with small curvature.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a positioning device for processing wind turbine blades, comprising: two arc-shaped outer shells;

[0008] A fixing component, which is disposed in the housing and is capable of fixing different curvature parts of the blade;

[0009] The fixing component includes a fixing shell disposed in the outer shell, and the fixing shell is provided with multiple movable plates, which are hinged together.

[0010] Preferably, the fixing assembly further includes telescopic rods hinged to both sides of the fixing housing. The telescopic ends of the telescopic rods are movably connected to the movable plates near the edge via a rotating shaft. By setting the telescopic rods, the movable plates at the edge can be limited when multiple movable plates make corresponding angle adjustments for the curvature of the blade. At the same time, the movable plates can be supported after adjustment to prevent the hinged movable plates from shaking during blade processing and to maintain the stability of the blade.

[0011] Preferably, the surface of the movable plate is designed with openings, and a vertical rod is fixedly connected inside the openings of the movable plate. An electric suction cup is installed above the vertical rod via a ball seat. By using the vertical rod in conjunction with the electric suction cup, the blade can be squeezed and adsorbed to fix it, thereby improving the stability of the blade during processing.

[0012] Preferably, a damper is fixedly connected to the inner bottom of the fixed shell, and the telescopic end of the damper is fixedly connected to the movable plate in the middle. The damper can reduce the pressure on the movable plate when it is pressed down by the blade, and prevent the blade from falling suddenly and causing damage to the hinge.

[0013] Preferably, a reinforcing plate is fixedly connected below each pair of movable plates. The reinforcing plate is elastically designed and made of stainless steel. The reinforcing plate can improve the connection effect between multiple movable plates and also assist in the angle adjustment of multiple movable plates.

[0014] Preferably, the inner wall of the outer shell is provided with a sliding groove, and a slide bar is slidably connected in the sliding groove. One side of the slide bar is fixedly connected to the fixed shell. By using the sliding groove and the slide bar, the fixed shell can be vertically displaced and limited.

[0015] Preferably, a push rod is fixedly connected to the inner wall of the outer shell and to one side of the fixed shell. The telescopic end of the push rod is fixedly connected to the fixed shell. The push rod can push the fixed shell to move towards the blade, thereby improving the fixing effect on the blade.

[0016] The beneficial effects of this utility model are:

[0017] 1. By setting multiple hinged movable plates in the fixing component, the curvature of different parts of the blade can be adapted when fixing the blade, thereby driving multiple uprights to adapt their angles. Combined with the electric suction cup, the blade can be fixed with multiple curvatures, which can effectively ensure the stability of the blade during processing.

[0018] 2. The two semi-circular outer shells can assist in flipping the middle of the blade when the blade needs to be processed from multiple angles, preventing damage caused by excessive prestress in the middle when the blade is rotated at both ends. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In practical implementation: such as Figure 1-4 As shown, a positioning device for processing wind turbine blades includes: two arc-shaped outer shells 1;

[0026] Fixing component 3 is disposed in the outer casing 1 and can fix different curvature parts of the blade;

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the fixing component 3 includes a fixing shell 301 disposed in the outer shell 1, and a plurality of movable plates 304 disposed in the fixing shell 301, the plurality of movable plates 304 being hinged together; the fixing component 3 also includes a telescopic rod 303 hinged to both sides of the fixing shell 301, the telescopic end of the telescopic rod 303 being movably connected to the movable plate 304 near the side via a rotating shaft; the surface of the movable plate 304 is designed with openings, and a vertical rod 306 is fixedly connected to the opening of the movable plate 304, and an electric suction cup 307 is disposed above the vertical rod 306 via a ball seat; a damper 302 is fixedly connected to the inner bottom of the fixing shell 301, and the telescopic end of the damper 302 is fixedly connected to the movable plate 304 in the middle; a reinforcing plate 305 is fixedly connected below every two movable plates 304, the reinforcing plate 305 being elastically designed, and the reinforcing plate 305 being a stainless steel plate;

[0028] First, the staff uses hoisting equipment to hoist the blade above the outer shell 1. Then, the blade is slowly lowered. As the blade descends, the surface of the blade first contacts the electric suction cup 307. At this time, the electric suction cup 307, which is connected to the upright 306 through the ball seat, will adjust itself by pressing the blade with the curvature and fit the curved surface of the blade. As the blade continues to be pressed down, the central movable plate 304 moves down. At this time, the other movable plates 304 that are hinged to each other will also adjust their angles as the central movable plate 304 moves down, so that the angles of multiple uprights 306 are adapted to the curvature of the corresponding blade parts. Until the blade moves down to be completely in contact with multiple electric suction cups 307, the electric suction cups 307 adhere to the surface of the blade, and the telescopic rod 303 opens to support the two movable plates 304 on the side.

[0029] It should be noted that the electric suction cup 307 is a relatively mature product in the existing technology. Its internal structure and how it performs adsorption or detachment operations can be found on the webpage, and the applicant will not elaborate on it here.

[0030] After the blade is placed in the lower outer shell 1, the staff can use the hoisting device to lift the upper outer shell 1 again and connect it to the lower outer shell 1. At this time, the fixing component 3 in the upper outer shell 1 can use the above method to make the multiple uprights 306 and the electric suction cup 307 adaptively adjust their angles according to the curvature of the upper part of the blade.

[0031] It should be noted that when personnel use hoisting equipment to connect the upper outer shell 1 and the lower outer shell 1, bolts or other structures that promote each other and provide a stable connection can be used to lock the connection between the two outer shells 1.

[0032] The inner wall of the outer shell 1 is provided with a sliding groove 4, and a sliding strip 5 is slidably connected in the sliding groove 4. One side of the sliding strip 5 is fixedly connected to the fixed shell 301. A push rod 2 is fixedly connected to the inner wall of the outer shell 1 and to one side of the fixed shell 301. The telescopic end of the push rod 2 is fixedly connected to the fixed shell 301.

[0033] Once the upper and lower electric suction cups 307 are in contact with the blade surface, the push rods 2 in the two outer shells 1 can be opened and the two fixed shells 301 can be pushed against each other, which can help fix the blade. At this point, the blade positioning operation is completed.

[0034] It should be noted that by setting two semi-circular outer shells 1, this device can also be applied to the middle of the blade. When the angle of the blade is adjusted by the operator for multi-faceted processing, a toothed belt is set on the surface of the outer shell 1, and together with a series of other support and limiting structures and gear drive structures, this device can assist the blade to flip. This can effectively prevent the problem of excessive torque in the middle of the blade caused by the traditional method of only supporting and flipping the two ends of the blade, which can easily lead to damage to the middle of the blade.

[0035] Working Principle: In actual use, the operator first uses hoisting equipment to lift the blade above the outer casing 1, and then slowly lowers the blade. As the blade descends, its surface first contacts the electric suction cup 307. At this time, the electric suction cup 307, connected to the uprights 306 via the ball seat, will adjust itself by pressing against the curvature of the blade and fit against its curved surface. As the blade continues to press down, the central movable plate 304 moves down. At this time, the interlocking gas movable plates 304 will also adjust their angles as the central movable plate 304 moves down, so that the angles of the multiple uprights 306 are adapted to the curvature of the corresponding blade parts, until the blade moves down to be completely in contact with the multiple electric suction cups 307. Afterwards, the electric suction cup 307 adheres to the surface of the blade, and the telescopic rod 303 opens to support the two movable plates 304 on the side. After the blade is placed in the lower outer shell 1, the operator can close the upper outer shell 1 and the lower outer shell 1. At this time, the fixing component 3 in the upper outer shell 1 can use the above method to make the multiple uprights 306 and the electric suction cup 307 adaptively adjust their angles according to the curvature of the upper part of the blade. After the electric suction cups 307 in both the upper and lower parts are in contact with the surface of the blade, the push rods 2 in the two outer shells 1 can be opened and the two fixing shells 301 can be pushed against each other to facilitate the fixing of the blade. The blade positioning operation is then completed.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
